Magnitude 94.56 Direction 198.41^@ 2 .d.p. I will do this problem using unit vectors: We know the magnitude of A and B. Given that we can look at the magnitude of the vector as being the …

How do you solve #5/f=35/21#? How do you determine if the equation #y = 1.7 (1.06)^x# represents exponential growth or decay? How to find the x and y-intercept given #3y=-6x+3#? …

Explanation: The dot product of two vectors is the sum of the products of the corresponding coefficients of the unit base vectors.

Please see a Proof in the Explanation. Recall that, foe any vector vecx, |vecx|^2=vecx*vecx. Therefore, for vecu and vecv, we have, |vecu+vecv|^2=(vecu+vecv)*(vecu ...

Mar 18, 2016 · A line passes through # (3 ,2 )# and # (7 ,3 )#. A second line passes through # (1 , 4 )#. What is one other point that the second line may pass through if it is parallel to the first …

Explanation: Given two non aligned vectors #vec u# and #vec v# the cross product given by #vec w = vec u times vec v# is orthogonal to #vec u# and #vec v#

How do I find all the vectors of V when U= (-1,3,2) and W= (1,1,-1) and what geometric figure does the outcome of V from?

What is the equation of the line that passes through # (-2,3)# and is parallel to #2x+3y=6#?

Jan 30, 2016 · There are two steps in a solution: finding the slope and finding the y-intercept. This particular line is the horizontal line y=5. First step is to find the slope: m = (y_2-y_1)/(x_2-x_1) …

Let #f (x) = x / (x^2+1)#, how do you use the first derivative test to determine which critical numbers, if any give relative extrema?
